Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ...
Various resistor types of different shapes and sizes. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
SMD resistors on the backside of a PCB. Pass current in proportion to voltage and oppose current. Resistor – fixed value Power resistor – larger to safely dissipate heat generated; SIP or DIP resistor network – array of resistors in one package; Variable resistor Rheostat – two-terminal variable resistor (often for high power)
High value resistors (HVR) are electronic components used for special applications, such as in bio-medical systems, measurement equipment and some condenser microphones. While discrete resistors in the range of few tens of megohm are very common, making giga-ohm range resistors is more complicated.
The meter comprised a moving coil meter, voltage and precision resistors, and switches and sockets to select the range. The first Avometer had a sensitivity of 60 Ω/V, three direct current ranges (12 mA, 1.2 A, and 12 A), three direct voltage ranges (12, 120, and 600 V or optionally 1,200 V), and a 10,000 Ω resistance range. An improved ...
One of the functions of many types of multimeters is the measurement of resistance in ohms.. The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt (V), applied to these points, produces in the conductor a current of one ampere (A), the conductor not being the seat of any electromotive force.
